[Zope] Effective Rights

[Mario Lang]

Hi.

Is there any way to calculate a roles effective rights on a object in Zope?
I currently have the situation that I can access two DTML documents
in a folder anonymously, and two other DTML documents only with manage users.
Trying to track the problem down, but I dont get it right.

What about this acquire permission settings checkbox?
Is there any special behavior when I added a local role in a
folder?
Can this affect acquisition of permissions of e.g. the anonymous role?

CYa,
    Mario
